    Description

    K145 is a selective, substrate-competitive and orally active SphK2 inhibitor with an IC50 of 4.3 µM and a Ki of 6.4 µM. K145 is inactive against SphK1 and other protein kinases. K145 induces cell apoptosis and has potently antitumor activity[1].

    IC50 & Target

    IC50: 4.3 µM (SphK2)[1]
    Ki: 6.4 µM (SphK2)[1]

    In Vitro

    K145 (0-10 µM; 24-72 hours; U937 cells) treatment significantly inhibits the growth of U937 cells in a concentration-dependent manner[1].
    K145 (10 µM; 24 hours; U937 cells) treatment significantly induces apoptosis in U937 cells[1].
    K145 (4-8 µM; 3 hours; U937 cells) treatment decreases the phosphorylation of ERK and Akt[1].
    Treatment with K145 (10 µM) causes a decrease of total cellular S1P without significant effects on ceramide levels[1].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Result: Significantly inhibited the growth of U937 cells in a concentration-dependent manner.

    Apoptosis Analysis[1]

    Cell Line: U937 cells
    Concentration: 10 µM
    Incubation Time: 24 hours
    Result: Significantly induced apoptosis in U937 cells.

    Western Blot Analysis[1]

    Cell Line: U937 cells
    Concentration: 4 µM, 8 µM
    Incubation Time: 3 hours
    Result: Phosphorylated ERK and Akt were decreased.
    In Vivo

    K145 (50 mg/kg; oral gavage; daily; for 15 days; BALB/c-nu mice) treatment significantly inhibits the growth of U937 tumors in nude mice[1].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: BALB/c-nu mice injected with U937 cells[1]
    Dosage: 50 mg/kg
    Administration: Oral gavage; daily; for 15 days
    Result: Oral gavage; daily; for 15 daysInhibited the growth of U937 tumors at 50 mg/kg dose and no apparent toxicity was observed.
